Valve Seat Grinder

Lapping Machine DX75480 is equipped with spindles, which
tips have a different conical shape in order to adapt to the different
valve seats to be grinded.
The choice of the right conical angle allows precision grinding on
the right spot of the cone damaged by the small ball hitting action.
The grinding operation has to be done using the small grinding
paper strips, which should be positioned between the spindle and
the valve seat (on top of the valve seat).
The grinding strips are of different grinding action, from the raw one
to the very fine one for end-lapping and are of the right size to suite
the valve seat.
